[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example: Figure 1-Figure 8 As shown, the present invention provides a technical solution for an LED display light box with a multi-angle display function, including a light box body 1 and a controller, characterized in that: a top cover 11 is arranged above the light box body 1, a base 12 is installed at the bottom of the light box body 1, a wall hanging surface is arranged on the side of the light box body 1, a plurality of groups of LED light strips are installed around the light box body 1, the light box body 1 includes an outer display box 2, a limit ring 21, an imaging component 4 and a driving component 3 are installed inside the outer display box 2, a plurality of groups of convex mirrors 22 are arranged on the limit ring 21, the driving component 3 cooperates with the imaging component 4, the imaging component 4 cooperates with the convex mirror 22, and the imaging component 4 can present an image on the outer display box 2 through the convex mirror 22;

[0032] Therefore, when the device is in use, the device can be hung on a wall or placed on the ground. When in use, the staff needs to upload the material to be displayed to the device, and then start the device to display the material on the outer display box 2 through the imaging component 4, so that passers-by can observe the material displayed by the device through the outer display box 2. At the same time, because the device is provided with multiple display surfaces 23, the device can promote different materials at the same time, or only promote one material. When displaying a group of materials, the device will play the corresponding sound of the material so that passers-by can better understand the displayed materials. At the same time, through the multiple display surfaces 23, passers-by can understand the material from different angles when passing by, and the device displays multiple different materials. When the device is used, the corresponding voice introduction will not be provided, but the same music can be matched with multiple different materials to attract more passers-by. At the same time, because the device is provided with multiple display surfaces 23, passers-by can see different materials without walking to different angles. The device can also drive the imaging component 4 through the driving component 3 to adjust the residence time of different materials so that passers-by can better observe the content on the display surface 23. At the same time, dust will be deposited on the device if it is placed indoors or outdoors for a long time. When dust exists on the display surface 23, passers-by will not be able to achieve an ideal viewing effect when viewing the device. The cleaning component 5 and the scraping component 6 of the device can clean the dust on the display surface 23, making the display effect of the display surface 23 better.

[0033] like Figure 1-Figure 5 As shown, in this embodiment, specifically, multiple display surfaces 23 are provided on the outer display box 2, and a limiting groove 24 is provided between each group of the display surfaces 23. A cleaning component 5 is installed inside the limiting groove 24, and the cleaning component 5 can clean the display surface 23. A holographic film is installed on the inner wall of each display surface 23, and the holographic film, the convex mirror 22 and the imaging component 4 are located on the same horizontal plane. Black films are provided on the inner and outer surfaces of multiple groups of the display surfaces 23, and each group of the holographic films is located between each group of black films;

[0034] When the outer display box 2 is in use, one is to facilitate the display of the picture, and the other is to protect the internal equipment. When in specific use, because the outer display box 2 is provided with multiple display surfaces 23, passers-by can observe the displayed content through the multiple display surfaces 23. When displaying materials, it is only necessary to start the imaging component 4 so that the image output by the imaging component 4 passes through the convex mirror 22 and is displayed on the holographic film. The material displayed on the holographic film will appear in a 3D state, so that when passers-by observe the material on the device, it can fully mobilize people's curiosity. The cleaning component 5 in the limiting groove 24 can clean the display surface 23 of the device, so that the display surface 23 is always in a clean and bright state, and the black film on the display surface 23 is to highlight the material displayed on the holographic film.

[0035] like Figure 1-Figure 2 As shown, in this embodiment, specifically, multiple groups of installation grooves are respectively provided inside the top cover 11 and the base 12, and speakers 13 are respectively installed inside the multiple groups of installation grooves. The multiple groups of speakers 13 are respectively connected to the controller, and the multiple groups of speakers 13 cooperate with the imaging assembly 4;

[0036] When the device displays the material, it can cooperate with the displayed material through the speaker 13 so that people can better understand the displayed content. When used specifically, because the device is provided with multiple display surfaces 23, the device can promote different materials at the same time, or only promote one material. When displaying a group of materials, the device will play the corresponding sound of the material so that passers-by can better understand the displayed material. At the same time, through the multiple display surfaces 23, passers-by can understand the material from different angles while passing by. When the device displays multiple different materials, the device will not cooperate with the corresponding voice introduction, but can match the same music for multiple different materials in order to attract more passers-by.

[0037] like Figure 1-Figure 2 and Figure 8 As shown, in this embodiment, specifically, the cleaning component 5 includes a slider 51, the slider 51 is installed inside the limiting groove 24, and tension springs 52 are installed at both ends of the slider 51, and the other ends of the tension springs 52 are respectively connected to the upper end and the bottom end of the limiting groove 24, and multiple groups of the tension springs 52 are respectively connected to the controller, and a connecting plate 53 is installed between two adjacent groups of the sliders 51. The connecting plate 53 is installed with a wall scraping component 6 on one side close to the display surface 23, and the wall scraping component 6 can clean the display surface 23;

[0038] When in use, the cleaning component 5 can cooperate with the scraper component 6 to clean the display surface 23 of the external display box 2, so that the display surface 23 can always be in a clean state. In specific use, when all the tension springs 52 located above are contracted, the connecting plate 53 will be driven to move upward, and then the scraper component 6 will be driven to move together, because the scraper component 6 is in contact with the display surface 23, and the display surface 23 will be cleaned during the movement. When all the tension springs 52 located below are contracted, the connecting plate 53 will be driven to move downward, and then the scraper component 6 will be driven to move downward again, and then the display surface 23 will be cleaned again. Repeated reciprocating processing can better clean the display surface 23.

[0039] like Figure 8 As shown, in this embodiment, specifically, when the tension spring 52 located at the top is energized: it can stretch the slider 51 to move upward;

[0040] When the tension spring 52 at the bottom is energized, it can pull the slider 51 to move downward.

[0041] Therefore, when the device is in use, the upper or lower stretch spring 52 can be energized respectively, so that the upper or lower stretch spring 52 can be contracted, thereby pulling the connecting plate 53 and the wall scraper assembly 6 on the connecting plate 53. When in use, it is only necessary to energize the upper stretch spring 52 uniformly, so that the upper stretch spring 52 can be contracted at the same time, thereby driving multiple groups of connecting plates 53 and wall hanging assemblies to move downward to the display surface 23. After a certain period of time, the lower stretch spring 52 can be energized uniformly, so that the lower stretch spring 52 can be contracted, thereby driving the connecting plate 53 and the wall scraper assembly 6 to move downward, thereby cleaning the display surface 23 again. The reason why the spring can contract after being energized is that when the stretch spring 52 is energized, each turn of the spring is equivalent to a circular current, and the current direction in each turn of the spring is the same. It can be seen that the same-direction currents attract each other, and each turn of the spring attracts the adjacent spring, so the spring as a whole will contract.

[0042] like Figure 6-Figure 7 As shown, in this embodiment, specifically, the wall scraping assembly 6 includes two groups of rubber plates 61, multiple groups of nozzles 62 are installed between the two groups of rubber plates 61, and multiple groups of nozzles 62 are equidistantly installed between the two groups of rubber plates 61. The two groups of rubber plates 61 can contact the display surface 23, and a water pipe is arranged inside the connecting plate 53, and the input end of the nozzle 62 is connected to the water pipe. A water storage tank 14 is installed inside the light box body 1, and the water storage tank 14 is connected to the water pipe;

[0043] When the wall scraping assembly 6 of the device is in use, it can clean the display surface 23 through its two groups of rubber plates 61. Because the two groups of rubber plates 61 of the device are in contact with the display surface 23, the wall scraping assembly 6 will be in an inclined state when moving back and forth, so as to scrape off the dust on the display surface 23. In the scraping process, the nozzle 62 will also spray a certain amount of cleaning liquid onto the display surface 23, so that the rubber plates 61 can achieve a better cleaning effect when cleaning the display surface 23. At the same time, the rubber plates 61 will also scrape off the cleaning liquid sprayed on the display surface 23 to prevent residual water stains from still adhering to the display surface 23 and affecting the imaging effect.

[0044] like Figure 4 As shown, in this embodiment, specifically, the driving component 3 includes a driving motor 31, and a supporting platform 32 is installed at the output end of the driving motor 31. A plurality of imaging components 4 are installed above the supporting platform 32. The imaging components 4 are projectors 41. The output ends of the projectors 41 are respectively facing one side of the convex mirror 22, and the output ends of the projectors 41 and the convex mirror 22 are located in the same horizontal plane;

[0045] When in use, the driving component 3 of the device can drive the imaging component 4 to move, thereby changing the position where different materials are displayed. When in use, the driving motor 31, under the control of the controller, can drive the supporting platform 32 to rotate 45 degrees after a certain period of time, so that a certain group of imaging components 4 can move to the position of the next group, and then when different materials are put in, the materials can be continuously displayed on multiple display surfaces 23 respectively, so that pedestrians passing by can easily understand the materials displayed by the device.

[0046] like Figure 4 As shown, in this embodiment, specifically, each group of the projectors 41 is provided with an infrared sensor, and the end cover ground is provided with multiple groups of control points, each group of the infrared sensors cooperates with each control point, and the drive motor 31 is connected to the controller;

[0047] Because eight groups of imaging components 4 are arranged on the supporting platform 32, but two surfaces of the outer display box 2 are combined into a wall-hanging surface, and thus two groups of imaging components 4 will not form an image when outputting toward the wall-hanging surface. When the infrared sensor on the projector 41 senses the two groups of reference points on the wall-hanging surface, the two groups of projectors 41 in front of the wall-hanging surface will not work. At the same time, it also provides the projector 41 with time to suspend heat dissipation, thereby preventing the projector 41 from working all the time and causing internal overheating, and also reducing certain resource consumption.

[0048] like Figure 1 As shown, in this embodiment, specifically, when the projector 41 projects the same material: the controller can control the speaker 13 to play the corresponding sound;

[0049] When the projector 41 projects different materials: the controller turns off the speaker 13;

[0050] The device can promote different materials at the same time, or only one material. When displaying a group of materials, the device will play the corresponding sound of the material so that passers-by can better understand the displayed materials. At the same time, through the multi-sided display surface 23, passers-by can understand the material from different angles while passing by. When the device displays multiple different materials, the device will not cooperate with the corresponding voice introduction, but can match the same music for multiple different materials to attract more passers-by.

[0051] like Figure 1 As shown, in this embodiment, specifically, the controller is installed on the inner bottom surface of the light box body 1, a control panel is installed above the end cover, a protective cover is provided outside the control panel, and the control panel is connected to the controller;

[0052] Therefore, when the device is in use, each component in the device can be controlled by the controller. At the same time, because the controller is connected to the control panel, the staff can also control the device through the control panel.

[0053] Working principle: When the device is in use, it can be hung on a wall or placed on the ground. When in use, the staff needs to upload the material to be displayed to the device, and then start the device to display the material on the outer display box 2 through the imaging component 4, so that passers-by can observe the material displayed by the device through the outer display box 2. At the same time, because the device is provided with multiple display surfaces 23, the device can promote different materials at the same time, or only promote one material. When displaying a group of materials, the device will play the corresponding sound of the material so that passers-by can better understand the displayed materials. At the same time, through the multiple display surfaces 23, passers-by can understand the material from different angles when passing by, and the device displays multiple different When the device displays materials, the device will not provide corresponding voice introductions, but can match the same music for multiple different materials in order to attract more passers-by. At the same time, because the device is provided with multiple display surfaces 23, passers-by can see different materials without walking to different angles. The device can also drive the imaging component 4 through the driving component 3 to adjust the time that different materials stay so that passers-by can better observe the content on the display surface 23. At the same time, dust will be deposited on the device if it is placed indoors or outdoors for a long time. When there is dust on the display surface 23, passers-by will not be able to achieve an ideal viewing effect when viewing the device. The cleaning component 5 and the scraping component 6 of the device can clean the dust on the display surface 23, making the display effect of the display surface 23 better.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
